A structural model of mode-activity choice: The case of commuter rail in a medium-size metropolitan area

Commuters in a medium size city may change how they travel from day to day during the week. A structural equations model is developed to examine commuter’s planning decisions about activities and modes during a work day. The model is applied to the problem of selecting commuter rail in the Piedmont Triad region of North Carolina. On a typical weekday, a commuter’s mode choice is affected by activities at the destination. However, when the commuter is faced with a mix of travel modes over time, the mode choice becomes a significant predictor of non-work/school activities.
